Ask HN: What Skills to Acquire in 2020?

I like your question and I am interested into other answers as well. I think the answer depends on the role you want to fit in.

I can tell you, that I will learn portuguesse in 2020 as my longterm goal is, to live in portugal and I will set the right foundation next year.

Depends what area you work in but as you are on this site I assume it's something nerdy :) I would like to be better at graphic design, nothing to complex, just the ability to design better icons, favicons, button graphics, blog post banners etc.

civic participation and community organization

Better Finance skills, meal planning, creating good habits for completing side projects
